Doubt much will come out of this investigation? What can the SEC do to assist global investors on a ghost company not registered in the USA?
In Garza's case the SEC (and the FBI and other alphabet agencies) went through all the online shit - yes, including Bitcointalk posts - trying to figure out who's involved. If some of those Bitconnect shills on youtube can be found in violation of securities laws - that would be a good outcome.
